Unveiling the orbital-selective electronic band reconstruction through the structural phase transition in TaTe
Natsuki Mitsuishi, Yusuke Sugita, Tomoki Akiba +8
Tantalum ditelluride TaTe belongs to the family of layered transition metal dichalcogenides but exhibits a unique structural phase transition at around 170 K that accompanies t…
Optical Hall response in spin-orbit coupled metals: Comparative study of magnetic cluster monopole, quadrupole, and toroidal orders
Tatsuki Sato, Yuma Umimoto, Yusuke Sugita +2
The optical Hall response is theoretically studied for spin-orbit coupled metals with ferroic orders of cluster-type magnetic multipoles. We find that different magnetic multipoles…
Antiferromagnet-semiconductor van der Waals heterostructures: interlayer interplay of exciton with magnetic ordering
Masaru Onga, Yusuke Sugita, Toshiya Ideue +4
Van der Waals (vdW) heterostructures have attracted great interest because of their rich material combinations.The discovery of two-dimensional magnets has provided a new platform…
Switching of band inversion and topological surface states by charge density wave
N. Mitsuishi, Y. Sugita, M. S. Bahramy +14
Topologically nontrivial materials host protected edge states associated with the bulk band inversion through the bulk-edge correspondence. Manipulating such edge states is highly…
Materials design of Kitaev spin liquids beyond the Jackeli-Khaliullin mechanism
Y. Motome, R. Sano, S. -H. Jang +2
The Kitaev spin liquid provides a rare example of well-established quantum spin liquids in more than one dimension. It is obtained as the exact ground state of the Kitaev spin mode…
Antiferromagnetic Kitaev Interactions in Polar Spin-Orbit Mott Insulators
Yusuke Sugita, Yasuyuki Kato, Yukitoshi Motome
A bond-directional anisotropic exchange interaction, called the Kitaev interaction, is a promising route to realize quantum spin liquids. The Kitaev interactions were found in Mott…
Band crossings in honeycomb-layered transition metal compounds
Yusuke Sugita, Yukitoshi Motome
Two-dimensional electron dispersions with peculiar band crossings provide a platform for realizing topological phases of matter. Here we theoretically show that the -orbital m…
Electronic band structure of 4d and 5d transition metal trichalcogenides
Yusuke Sugita, Takashi Miyake, Yukitoshi Motome
Transition metal trichalcogenides (TMTs), a family of van der Waals materials, have gained increasing interests from the discovery of magnetism in few-layer forms. Although TMTs wi…
Multiple Dirac Cones and Topological Magnetism in Honeycomb-Monolayer Transition Metal Trichalcogenides
Yusuke Sugita, Takashi Miyake, Yukitoshi Motome
The discovery of monolayer graphene has initiated two fertile fields in modern condensed matter physics, Dirac semimetals and atomically-thin layered materials. When these trends m…
Topological Insulators from Electronic Superstructures
Yusuke Sugita, Yukitoshi Motome
The possibility of realizing topological insulators by spontaneous formation of electronic superstructure is theoretically investigated in a minimal two-orbital model including bot…
